GEOS

The definition of GEOS

The graphic environment
operating system is a
lightweightOS
with a GUI. It runs on
several different processors, including the
65xx (different versions for
different machines -- there are versions for the C64, the C128, and
the Apple ][, each utilizing the relevant custom chip
sets), the x86 (although the x86
version is made to run on top of
MS-DOS (or
PC-DOS or
DR-DOS) and is not strictly a full
OS or a window manager,
rather it is somewhat in between, like
Windows 3.1) and
numerous different PDAs,
embedded
devices, and hand-held machines. It was originally
designed by Berkeley Softworks (no real relation to the
Berkeley of UNIX fame) but is
currently in a more interesting state: the company
GeoWorks develops and promotes development of GEOS for
hand-held devices, PDAs, & and embedded devices and
owns (but has ceased further development on) the x86
version. The other versions are owned (and possibly still
being developed) by the company CMD.
